The Future of Semantics on the Web

A Keynote at the Web Science Conference, 2018, held at the VU Amsterdam [1]. This describes in the main the output of the Semantic Technology Institute International (STI2) Summit (for senior researchers in the Semantic Web field) held in Crete in September, 2017 [2].

condemned to repeat it.” George Santayana 1905/06

“People will not look forward to posterity, who
never look backward to their ancestors.”

Agents in Original Semantic Web
“The real power of the Semantic Web will
be realized when people create many
programs that collect Web content from
diverse sources, process the
information and exchange the results
with other programs. The effectiveness of
such software agents will increase
exponentially as more machine-readable
Web content and automated services
(including other agents) become available.
The Semantic Web promotes this synergy:
even agents that were not expressly
designed to work together can transfer
data among themselves when the data
come with semantics.”
Tim Berners-Lee, James Hendler and Ora Lassila 14

Linked Open Data
Use1. URIs to name (identify) things.
Use2. HTTP URIs so that these things can be
looked up (interpreted, “dereferenced”).
Provide useful information about what a3.
name identiﬁes when it’s looked up, using
open standards such as RDF, SPARQL, etc.
Refer to other things using their HTTP URI4. -
based names when publishing data on the
Web.

Data Consumption
• Is still problematic
• No good paradigm and best practices for
making data good for a purpose

Ontology engineering and data
mapping
• Ontology engineering and data mapping, as
done today, are complex and do not scale
• Matching/linking entities is still too complex
• Keeping mappings up to date as data
changes at source
• This makes it hard to come up with reliable
“data architecture” that uses LOD for
enterprise applications

Conclusions 1/3
Main role beneﬁt of semantics is its ability to sit•
between the machine and humans:
Raising the level of discourse–
Supporting interoperability–
Enabling automation–
What has changed•
Scale–
Industrial take– -up
Future•
Adapting to ever changing context–
Hitting the sweet spot between reasoning power and–
simplicity
